I have to wonder why Star Trek surgeons wear those red suits sometimes. I mean, Crusher once said that there is a special type of field in surgical rooms that stops people getting infections - and the suits can't be for that anyway, because they don't cover your nose or mouth. Is it just some kind of surgeon fashion?

Plotline

When Vedek Bareil is fatally injured, Bashir must use ever more invasive medical procedures to keep him alive. Eventually he begins to question the ethics of what he is doing - but can Kira face up to loosing the man she loves?
